Provide a level concrete slab. To prevent transmission of noise or vibration, slab should not be connected to building structure. Some sort of sound-absorbing material should be placed between the condenser and the slab. A good material to use is rubber and cork pad. For rooftop application, make sure the building construction can support the weight and that proper consideration is given to the weather-tight integrity of the roof. The condensing unit contains moving parts and can vibrate. Theref

1.Tubing should be cut square. Make sure it is round and free of burrs at the connecting ends. Clean the tubing to prevent contamination from entering the system. 2.Make sure that both refrigerant stop valves at the outdoor unit are closed. 3.Push the tubing into the fitting until it stops. This prevents flux from getting into the system. 4.Remove the cap and Schrader valve core from the service port to protect the valve seals. 5.Wrap a wet rag around the valve stub before brazing. 6.Braze t

Evacuation All new installations must be evacuated to a deep vacuum in order that all noncondensible gases and moisture are removed prior to charging the system. Air in a system causes high condensing pressure, which increases power consumption and reduces performance. The presence of moisture in a system can render it inoperable in a very short time. Proper evacuation assures a dry, uncontaminated system. Here is the recommended evacuation procedure: 1.Connect vacuum pump to both liquid and suc

The condensing unit rating plate and the tables of "Physical and Electrical Specifications / Outdoor Units" (Table 1 and 2) provide pertinent data necessary for the selection of proper size electrical service and over-current protection devices. Table 6 provides data on the minimum copper wire size as a function of supply wire length and circuit ampacity. Copper Wire Size - AWG (1% Voltage Drop) Supply Circuit

8.OPERATION Most single phase units are operated without start relay or start capacitor. Such systems should be off for a minimum of 5 minutes before restarting to allow equalization of pressures. The thermostat should not be moved to cycle unit without waiting 5 minutes. To do so may cause the compressor to stop on an automatic open overload device or blow a fuse. Poor electrical service can cause nuisance tripping in overloads or blow fuses. The compressor has an internal overload protector. U
